FHFA notes: The FHFA HPI is a broad measure of the movement of single-family house prices. The FHFA HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. FHFA describes its county indexes as developmental and subject to revision. The index does not give a dollar value for any home.

FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (1975 here). A decade's change is the index at the end of the decade divided by the index at the start, so it does not depend on the base year; the United States column covers the same years. Decades before 1975 are not shown.
